I'm still a virgin. Will a vibrator help me get ready for my
first time?

Short Answer:
Masturbating with a vibrator can help you get more comfortable with your
sexuality and become more familiar with the sexual responses of your body
and the sensations of genital stimulation and/or penetration. However,
having an intimate physical encounter with another person will be a
different type of experience.

Long Answer: Getting
yourself off with a vibrator is a relatively simple and straightforward
business. Getting it on with a flesh-and-blood person is a different
beast altogether. The key is communication: communicating your desires
and needs to your partner, and understanding theirs. Communication you
can't learn from a vibrator. But you can learn about what feels good to
you, and being comfortable with your own body and your sexual feelings
is essential preparation for being intimate with a partner. Do you like
direct clitoral stimulation, or deep penetration? These are good things
to know before you get into bed with someone.

A vibrator's controls are
very simple - on and off, fast or slow - and you remain in complete
control of the experience while stimulating yourself. A certain element
of sex involves giving up that control and sharing it with your partner.
This is also what makes sexual intimacy exciting and meaningful. A great
way to build trust and intimacy (not to mention arousal) with your
partner is to tell and show them what you enjoy sexually. That can mean
introducing them to your vibrator and incorporating it into your sex
play.
